Google crawl date using PHP source code. Google bot crawls every web site after a specific period. You can check that date using Google’s cache command in Google search engine. Here it is the example of Google cache.
http://64.233.183.104/search?q=cache%3Afree-computer-tips.info&sourceid=navclient-ff&ie=UTF-8&rlz=1B3GGGL_enPK238__238
I created PHP function which gets Google bot crawl date and returns in a form of string.
You can use these codes in your PHP applications.
Code are under the marks due to setting of page

function google_crawl_date($url){
  $output = file_get_contents('http://64.233.183.104/search?q=cache:'.
   urlencode($url).'&sourceid=navclient-ff&ie=UTF-8&rlz=1B3GGGL_enPK238__238');
  $match_expression = '/appeared on (.*). The 
  preg_match($match_expression,$output,$matches);
  if ($matches[1]=="") return "No Date found";
  else return $matches[1];
}

PHP programmers need sometimes current page URL to show or save in database. There is no built-in function exist in PHP to get current page url. I made a function to show current page URL.
I used the following built-in $_SERVER array in this function. If you want to show all element return by $_SERVER array then you can use these commands.
.
.
.
.

echo "
";
   print_r ($_SERVER);
   echo "
";

   echo currenturl();
?>

?>

How to get visitors IP address? If you want to get your web site visitor’s IP address then PHP provides you complete solution for this. I made a function to get IP address of visitor.
PHP Codes

.
.
.
.
.
.
function visitorip() {
    if (getenv(‘HTTP_CLIENT_IP’)) $ip = getenv(‘HTTP_CLIENT_IP’);
    elseif (getenv(‘HTTP_X_FORWARDED_FOR’))    $ip = getenv(‘HTTP_X_FORWARDED_FOR’);
    elseif (getenv(‘HTTP_X_FORWARDED’)) $ip = getenv(‘HTTP_X_FORWARDED’);
    elseif (getenv(‘HTTP_FORWARDED_FOR’)) $ip = getenv(‘HTTP_FORWARDED_FOR’);
    elseif (getenv(‘HTTP_FORWARDED’)) $ip = getenv(‘HTTP_FORWARDED’);
    else $ip = $_SERVER['REMOTE_ADDR'];
    return $ip;
}
echo “Your IP address is “.visitorip();
?>

In result web site visitor’s ip address will appear. In example above i made a function named visitorip() will check all conditions for getting ip and will return ip address. echo command of PHP will receive ip address will display on page.

Configuring your Gmail account in Microsoft Outlook would become as easy as 1, 2, 3 for you after reading the below mentioned step by step process. Gmail messages can now be retrieved with the help of any device or client which can provide POP support and Microsoft Outlook is one of those clients that offer POP support to their users. Just concentrate and read the every step carefully to understand the whole process:

POP Option Enabling in Gmail:

• First of all login to your Gmail account Then click on “Settings” option which can be seen on right top of your screen
• There you will find “Forwarding and POP / IMAP” option, click on it
• There an option i.e. “Enable POP for All Mails” or “Enable POP for Mail” should be clicked
• Now an action would be asked to choose after getting POP access from Gmail. Choose appropriate one that suits your need
• Check “Configure your POP client” and then a button saying “Save Changes” should be pressed

• We consider that you have already opened Microsoft Outlook 2007, click Tools Menu
• Click an option “E-mail Account”
• There you will see an option “Add a new e-mail account” select it and then click on the button “New”
• There you will be asked by the system to select server type. POP3 or POP option must be selected ….. then click on the option “Next”
• Now system will ask for necessary setting. Put on your desired / required setting including email address and password of your email
• Write “pop.gmail.com” as your incoming mail server and as the settings of outgoing mail server “smtp.gmail.com” must be written in the required field
• Then click on the button that says “More Settings . . .”
• Then click on the tab saying “Outgoing Server” and an option saying “My outgoing server (SMTP) requires authentication” must be checked by you. It will increase security and a password will be required to even send a single email from this Microsoft Outlook in addition to receiving email
• Then on the same screen, you will see a tab saying “Advanced”, click on it
• Here you will have to change port numbers for your incoming and outgoing mail server but first you need to check the appropriate box before assigning any value
• Incoming server should be set a port value as “465” and “995” port number should be set to outgoing mail server
• That’s it. You are done and finally have set up Gmail in Microsoft Outlook 2007.

Blocking access to undesirable Web sites through the use of Internet protocol filters has been a common government tactic since commercial Internet access first became available here in 1995. China and Saudi Arabia are believed to extend greater censorship over the net than any other country in the world under the pretext of information control.

Most of the blacklisted sites in Saudi Arabia are either sexually explicit or about religion, women, health, drugs and pop culture. They even block access to websites about bathing suits. So if you want to buy something to swim in, they seem to treat that as if it were pornographic in Saudi Arabia.

In China, webites containing sexually explicit content were among those blocked, but they also included sites on sensitive topics such as Tibet, Taiwan, and dissident activity. China also blocks access to Google News, Typepad and Blogger hosted blogs.

But what if an innocent website is accidentally blocked by your ISP or your government. There are always legitimate reasons to visit these blocked websites. We have listed a few methods to help you access blocked websites in school, college, office or at home.

Approach 1: There are websites Anonymizer who fetch the blocked site/ page from their servers and display it to you. As far as the service provider is concerned you are viewing a page from Anonymizer and not the blocked site.

Approach 2: To access the blocked Web site. type the IP number instead of the URL in the address bar. But if the ISP software maps the IP address to the web server (reverse DNS lookup), the website will remain blocked.

Approach 3: Use a URL redirection service like tinyurl.com or snipurl.com. These domain forward services sometimes work as the address in the the url box remain the redirect url and do not change to the banned site.

Approach 4: Use Google Mobile Search. Google display the normal HTML pages as if you are viewing them on a mobile phone. During the translation, Google removes the javascript content and CSS scripts and breaks a longer page into several smaller pages. [link] View this website in Google Mobile

Approach 5: Enter the URL in Google or Yahoo search and then visit the cached copy of the page. To retrieve the page more quickly from Google's cache, click "Cached Text Only" while the browser is loading the page from cache.

Approach 6: A recent Oreilly story on accessing blocked websites suggested an approach to access restricted web sites using Google language tools service as a proxy server. Basically, you have Google translate your page from English to English (or whatever language you like). Assuming that Google isn’t blacklisted in your country or school, you should be able to access any site with this method. Visit this site via Google Proxy

Approach 7: Anonymous Surfing Surf the internet via a proxy server. A proxy server (or proxies) is a normal computer that hides the identity of computers on its network from the Internet. Which means that only the address of the proxy server is visible to the world and not of those computers that are using it to browse the Internet. Just visit the proxy server website with your Web browser and enter a URL (website address) in the form provided.

The attack is actually quite simple.  First job is to be able to sniff data packets and like open Wi-Fi network or any other open network. Download Ferret to copy all the cookies flying through the air.  Finally, those cookies are cloned into browser – in easy point-and-click fashion - with a home-grown tool called Hamster.This story has been elaborated by Graham here

The attack can hijack sessions in almost any cookie-based web application and Graham has tested it successfully against popular webmail programs like Google’s Gmail, Microsoft’s Hotmail and Yahoo Mail.  He stressed that since the program just uses cookies, he only needs an IP address and usernames and passwords aren’t required.
He has also included a slideshow here:Gmail hacking at Blackhat
If you want to prevent your accounts from being hacked then force https throughout a gmail session.Change your http://mail.google.com bookmark to https://mail.google.com. Or type in the full URL in your browser starting with https://, or else your browser will assume http:To ensure that your entire gmail session uses https, grab the GmailSecure greasemonkey script:

Today an interesting advisory about some vulnerabilities affecting Orkut - the famous social networking website, owned by Google.
There are several cases like -Sometimes the application may lock out the user to the main page when an operation fails, asking the user to login again, but failing to logout the user while doing it. This could confuse the users into thinking that they logged out.
And Now a hacker can use this stage for hacking the users account.At this stage the "orkut_state" cookie can still be used to login successfully, even if the user logged out. This is probably due to a failure to mark the session as expired on the server side.
How to?-A Technical Description(Never use this info to hack any others  account)
On successful Orkut login, the following cookies are set:-
1. Domain: .www.orkut.com Cookie: orkut_state
2. Domain: .google.com Cookie: SID
